Not really: see gamma 265 on the plural of this neuter noun. Hesychius glosses the singular (as here) with the phrase th=s stafulh=s to\ e)/ndon, "the inside of the grape"; the Suda's e)/nduma looks like a slip. In any event, Latte on Hesychius s.v. regards these entries as stemming from Numbers 6.4 LXX (genitive case).
